Crave the Knot - Chapter 4: Modifications

How much time had passed?  Jake did not know.  However, the skylight in the
kennel in which he slept with his canine mates afforded him a view of the
moon, and it had completed at least four phase cycles since his arrival and
transformation from human boy into a breeding bitch.  After his initiation
night at the clubhouse, he received a gold tag on his leather collar that
read `Zero – Master Kevin, Owner'.  From that point onward, his training
had intensified.

Kevin placed headphones on Jake every afternoon after lunch.  He was then
injected with a cloudy liquid and sat in front of the TV in the living room
to stare at a swirling mass of color.  For two hours, he would listen to
the voice of his master as it burrowed into his mind and rewired his
consciousness.  It was as if he could leave his body.  He floated on
another plane and drank in the deep baritone tones of the man that was his
god now.

"Just a dog.  You are just a dog.  A bitch in heat.  You crave the knot.
You need the knot.  Obey your master.  You are just a dog."

The programming went further.

"Dogs do not talk.  Dogs bark.  They whine.  They growl.  But they never
use human speech.  You are just a dog.  You do not talk."

Jake's eyes became glassy as the swirling patterns continued.  His pupils
dilated, and his breathing slowed.  He could hear his heartbeat as it
pounded in his chest.  It became louder and louder and resonated like a
drum as the voice in his head continued.

"Just a dog.  You obey your master.  You do only what your master says.
Forget your past.  Embrace your new life.  Master is your god.  Bruce and
Tank are your lovers.  Crave their knots and accept their alpha seed."

Drool began to fall from Jake's mouth.  A long thin line of fluid glistened
from the side of his red and white pup mask as it slowly made its way to
the floor.  His body swayed side-to-side as he lost consciousness and
thought.

"Just a dog.  A bitch to be bred.  A bitch in heat.  Present your cunt.  It
radiates warmth.  It craves the knot.  Beg for the knot.  Obey your master.
You are just a dog."

When his master eventually appeared before him and removed his headphones,
he found he could not move until Kevin snapped his fingers.  His body was
still, and his limbs were like lead until the gesture was given.  At that
moment, his breath returned to him.  His surroundings became coherent, and
Jake immediately bowed to be caressed.

"You are doing very well, my pet," Kevin said.  "Turn around and let me see
those back paws."

Jake did as he was told, and Kevin inspected the pup's legs.  They had now
been tied back onto Jake's thighs for so long that the muscles had started
to atrophy.  However, sores had also formed unexpectedly.  The concern
Kevin had was real.  If the sores become infected, it could lead to more
severe issues.  Only one other human pup had experienced such a reaction,
and it had to be released from the club due to poor health.

"I think we need to go back to the doctor, Zero," Kevin said.  "This does
not look good."


The following morning, Jake found himself once again placed on the metal
table at Frank's house.  He had been heavily sedated and his pup gear
removed.  Before his legs were inspected, he was evaluated to see how his
body reacted to the loss of his testicles.  His dark body hair had started
to thin.  His beard growth had slowed, and Kevin had a much easier time
shaving his face.

"I see the skin on his sides has become tough and callused," Frank said as
he pinched at Jake's waist.

"Yes," Kevin said.  "He hardly ever gets scratches from the dogs anymore
when mating."

"That is a good thing!" Frank said as he rubbed Jake's face.  "I know you
said you are shaving him every few days.  Have you considered laser therapy
to remove the hair on his face?  If he is wearing his mask all the time,
there is no need to have it growing there."

"Can that be done here?" Kevin asked.

"Of course!" Frank replied with a chuckle.  "I will give him his first
treatment later today if you like."

"Please do," Kevin said.  "That way, I can just leave his pup hood on him
permanently."

"Very well," Frank said.  "Now let's see those legs."

Frank stretched out Jake's lower limbs.  The boy could feel the resistance.
His legs were stiff and reluctant to move after so long being strapped in a
bent position.  The doctor pursed his lips as he inspected the sores that
had formed.

"I'm afraid they are not getting better," Frank said.  "I know we discussed
this possibility.  Are you ok with an amputation?  I could remove both legs
below the knees.  It would take a little time for Zero to get used to the
feeling, but I think he would be better off and more healthy."

"Yes," Kevin said.  "I think that will be for the best.  Zero is a quick
learner.  He will adapt."

"Very well," Frank said.  "He will have to stay at the clinic for a week,
however.  This is a lot more involved than his previous surgery."

"I understand," Kevin said.  "And can you do the implant at the same time?"

"Absolutely!" Frank replied.  "We might as well do everything in one go."

Kevin smiled and walked over to Jake's face and petted it softly.

"Don't worry, my pet.  Everything will be ok.  Submit to your doctor and do
what he says."

"Zero trusts Master," Jake immediately replied.  "Zero will obey."

"Good dog," Kevin replied.

The room faded again.  Jake lost all sense of time and space.  The smell of
disinfectant passed through his nose.  A moment of pain followed by
coolness and tranquility.  He floated for a time.  His body felt more
balanced.  He spent time on his back where he was diapered and monitored.
He remembered the feeling that his legs were lighter and free.  At several
points, the sensation of heat on his face came into his mind, followed by
more sedation.  Time passed as he heard his master's voice in his head
again.

"Just a dog.  You obey your master.  You do only what your master says.
Forget your past.  Embrace your new life.  Master is your god.  Bruce and
Tank are your lovers.  Crave their knots and accept their alpha seed."

When Jake finally returned to reality and opened his eyes, he found himself
at home in his metal kennel in the back bedroom.  Both his legs had been
removed below the knee, and soft pads had been installed over where his
limbs now ended.  His face felt cool and hair free under his mask, and a
feeding tube in his nose led into his stomach.  A catheter in his soft cock
led to a large bag half full of urine, and the voice of his master was
calling to him.

"Wake up, Zero!"

Jake looked up.

"How are we feeling today?"

Jake barked.  He was sore, but the rehabilitation that followed in the next
few weeks helped him overcome it.  It took time, but eventually, the pup
learned to walk again.  In fact, he found he could get around much easier
with his useless lower limbs removed and the lengths balanced across his
body.  Before long, he could bound around the yard with Bruce and Tank, and
his quality of life had improved.  However, as Jake sat on the floor and
looked at the moon, he thought about the new sensation he had felt since he
returned from the doctor.  It started as a dull ache between where his
colon was and his balls used to be.  Jake noticed a small metal opening or
port in his taint as the pain subsided.  He had been curious and inspected
it but had no idea what it was.

In the morning, Jake awoke.  Bruce and Tank licked his body to groom him as
he got to his paws.  Once his alphas were sure he was presentable, Jake
followed them as they headed for the flap into the kitchen.  The pup had
his head in his dog bowl and was gobbling up his kibble next to his canine
mates when his master, Kevin, appeared in his thin boxers and t-shirt
carrying a small box.

"Good morning, pups!" Kevin announced.

Bruce and Tank both looked up and barked, and Jake followed suit.

"How are we feeling today, Zero?" Kevin asked.

Jake barked and shook his head in response.

"Bright-eyed and bushy-tailed, I see," Kevin replied.  "Well, today is a
special day.  You have finally healed enough that we can use a special
little device I had installed inside you.  I am sure you have noticed it."

Jake cocked his head and then looked down at his limb cock.

"Yes," Kevin said with a chuckle.  "That small metal opening between your
penis and cunt.  When you were at the doctor's office for your operation to
remove your legs, I had a small device installed inside you.  We are going
to try it out for the first time today.  Come, pet.  I need you to point
your ass at me and bend over."

Jake was curious but did as he was commanded.  As Tank and Bruce sat and
watched, the boy turned, pointed his ass at his master, and then leaned
down till his head was on the floor.  While doing so, Kevin pulled out a
large syringe filled with a cloudy fluid, similar to what was in the device
that Jake had used on the wall in the living room.  Kevin attached a small
needle to the end of the tube and then leaned over and located the small
port in Jake's taint.  Threading the syringe inside, Kevin applied some
pressure and then turned the device.  The needle locked into place.  He
then pushed the plunger, and the fluids began to flow inside Jake.

Jake felt the cool liquid as it entered his body.  It filled a compartment
inside him, and the expanding reservoir caused some pressure as it
inflated.

"A true bitch does not need to fuck itself to have artificial fluids pumped
inside it or creams applied to its cunt to attract its mates," Kevin said.
"With this device, I can fill you with your own female hormones, which will
slowly be excreted into your cunt through an internal tube.  Now you can
signal to any dog in the area that you are always in heat and ready for
mounting.  I only need to top you off once a week.  What do you think about
that?"

Jake groaned as the fluids continued to be pumped into him.  No longer
would he have to use the fake phallus in the living room.  His
transformation into a true canine bitch was almost complete.

When Kevin pushed the last of the fluids inside the pup, he twisted the
needle and then slowly extracted it.  Jake could feel pressure inside him.
The inflated reservoir sat beside his prostate, applying a gentle but
pleasant pressure.

"It might take some getting used to," Kevin said as he patted Jake's ass.
"But I know your mates will appreciate you being ready at all times.  Which
reminds me!"

Kevin pulled the plug tail from Jake's ass and then turned and retrieved a
new slender, black tail from the counter.

"I also had a strong magnet installed in your lower back."

Kevin held the base of the new tail near Jake, and it jumped and attached
firmly to him.

"Now you have a permanent tail that does not need to be removed!" Kevin
said.  "How do you feel about that?"

Jake lifted his body and looked back.  He wagged his ass, and the tail
flopped back and forth.

"Good, Zero," Kevin said as he patted Jake's ass.  "I think you should go
outside and try out that upgraded cunt with your mates."

Jake barked twice and turned to drink some water before following the dogs
out into the yard.  Bruce was fascinated by the new tail and had his nose
right behind Jake as the boy trotted down the grassy area next to the
fenced kennel.  It was then that the dog noticed the scent.  From inside
its bitches cunt, Bruce could detect the odor of the pheromones as they
slowly saturated Jake's rectum.  The Shepard's red cock twitched.  Bruce
pushed his nose between Jake's ass and let his long tongue run up and down
it.  Jake paused and shuttered as he felt his lover's attention.  He spread
his legs and leaned over to present his cunt as he felt the warm and wet
tongue push inside him and lap at his juices.

Jake closed his eyes and breathed deeply.  The morning sun caressed his
back as his ass was worshiped.  The loud slurping sounds became more
frequent as Bruce became excited.  The fluids inside Jake were causing the
dog's brain to go into overdrive.  Soon, its dick was hard and dripping,
and in one movement, the beast leaped onto the boy's back and latched its
legs around Jake's waist.  Bruce's hind legs rapidly moved back and forth
as his cock shot out copulatory fluids, which coated the boy's crack.  With
a shove, the organ went inside Jake's cunt, and the boy could feel the
sawing back and forth as the dog pushed deeper and deeper.

The boy was in heaven.  He longed to be mounted by the beast.  He squeezed
his ass to feel the expanding shaft as it pushed inside.  Soon, he would
feel the bulbous knot... and he needed that knot.  He craved the knot.
When it hit his ass, he pushed back and relaxed to accept it.  A momentary
searing pain shot through him as it passed over the lips of his cunt, but
as it locked into place and expanded over his prostate, the boy groaned
loudly.  Clear fluids poured from his limp prick as his boy juices were
expelled.

Bruce had knotted his bitch.  As the organ completed its expansion, it
slowed and started to pump copious amounts of warm canine cum into Jake.
The feeling was unmistakable to the boy.  He could almost imagine the pups
being delivered into his waiting womb.  His belly expanded as his ass was
filled, and Jake's hands clinched inside the mittens he wore.

As Bruce turned, the pressure caused Jake to have an internal orgasm.  As
the fireworks shot off in his brain, he opened his mouth and let the drool
fall onto the blades of grass below.  A tongue then appeared and forced its
way into the boy's mouth.  Jake opened his eyes to see Tank before him,
making out with him.  The boy lifted open his snout and let the dog push
deeper.  He could feel the warm air that moved over his head as Tank
panted.  The dog was excited as he watched his brother sit ass to ass with
the bitch and fill it with cum.  His dog cock was hard and dripping, but he
would have to wait.

When the fist-sized knot inside Jake finally began to deflate, Bruce gave a
few tugs and then extricated himself from the boy's cunt.  The red cock
flopped onto the ground with a splash as cum poured from the boy's abused
hole.  Tank moved quickly to take his turn.  As the beast mounted the boy,
Jake could feel the weight of the Great Dane.  Tank was panting heavily as
his cock pulsed precum and pushed forward.  Finding its mark, the organ
slid deep into the boy, causing his breath to be expelled.  Jake caught
himself as his front body pushed forward off balance.  His mate was more
forceful today.

Tank took no time jackhammering his knot into the boy, and once it was
locked, he turned and let his tongue fall from his snout as he added his
seed to his brothers.  Jake could feel every pulse as it was delivered into
him.  The pressure of the knot was intense.  It completely crushed his
prostate and rested against the new reservoir of pheromones inside him.
The bag had shifted and pushed against his bladder, causing him to piss
onto the ground uncontrollably.

Tank finally decided it was time to lie down.  Jake knew the routine well.
He felt the tug on his insides and crawled backward on his paws as the
beast went for a shady spot next to the water trough.  As the dog
collapsed, Jake came with him, ass-to-ass, on his side.  His soft penis was
still dribbling urine as Bruce came over to lick his groin clean.  Jake let
his eyes close as he was still being impregnated.

When the boy awoke, his lovers were curled up beside him.  The river of cum
that had expelled itself from the boy's ass when Tank finally pulled free
had crusted over, and Jake felt the cool air as it moved across him.  He
reached over and caressed the side of Bruce.  He was a lucky pup to have
such caring mates.  His bladder felt full, though, so he pulled himself to
all fours and wandered around till he found a place to squat and relieve
himself.

"Well, don't you look cute," came a voice from behind him.

Jake turned around and saw a familiar form towering over him.  It was
Chuck, the gang leader that he had seen during his initiation night.  Next
to him, sitting patiently, was the bullmastiff that he owned, Zeus.

"You look much better without those useless limbs tied to you, Zero," Chuck
said.  "Come over here and let me pet you, boy!"

Jake barked and crawled over to the large, bald man.

"That's a good boy!" Chuck said as he scratched Jake's head and neck and
inspected him.  "That former boy dick of yours really has shrunk.  Before
long you will just have a tiny nub to piss out of."

Jake wagged his tail as the man spoke.  Zeus watched from the side, but his
ears perked up when Jake turned to the side to be petted.  There was a
smell in the air.  The beast could detect the cum from two other dogs but
mixed within was an intoxicating scent.  Zeus moved his head to the side.
The aroma was more pungent near this pup's ass.  A signal went off in the
dog's brain, and it began to salivate.  Its cock twitched and began to
emerge from the fur that protected it.  Zeus stood and moved its nose near
the boy's cunt.  There was no mistaking the odor.  This bitch was in heat.
The bouquet of pheromones began to drive the dog wild.

"See something you like, boy?" Chuck replied with a chuckle as he saw his
dog starting to hump the air.  "Well, get at it, then!"

Zeus looked up at its master as if to make sure it was permitted before he
lapped at Jake's ass twice and then pulled its frame up and over the boy.
Jake grunted as the weight fell on him.  The dog continued to hump the air
as its red canine cock lengthened and swelled.  Juices flew in ropes from
the tip as they coated the boy and then entered inside him.  This dog was
thicker than his mates, at least at the tip, and Jake groaned.  Bruce and
Tank woke up and walked over.  They whined at first, but with a firm
command from Chuck, they sat back and watched as their bitch was violated.

The swelling knot from Zeus pounded onto Jake's sore cunt.  It pushed
inside and out twice before the boy shoved his ass backward to tie to it.
The baseball inside him pulsed as cum shot from the cock into his insides
and mixed with the seed he had been bred with earlier.

"That's a good boy, Zeus!" Chuck replied.  "Show these two who is the alpha
dog in the pack."

"What do you think?" Kevin said as he walked outside and into the yard.

"Zero is looking really good!" Chuck replied.  "You were right.  It only
took a few seconds for Zeus to pick up the bitch's scent.  We need to have
this implant put in all the bitches in the club."

"I told you it would be an improvement," Kevin said with a laugh as he
walked over, watched as Zeus panted twice, and then jumped off Jake to turn
ass-to-ass with the boy.

"That's a good boy!" Chuck said as he petted his dog.  "Pump that bitch
full."

Zeus looked to be smiling as he looked up at his master in contentment.

"Are you bringing Zero to the monthly meeting?" Chuck asked.

"Yes, he will be there," Kevin replied.  "He needs to get to know the other
pups and bond with them.  I just needed to wait till his health had
stabilized."

"Excellent," Chuck replied as he moved to pat Jake's belly as it was filled
with cum.  "We will look forward to getting to know the bitch better.  By
the way, there will be a dominance challenge, so be prepared to place some
wagers."

"Oh?" Kevin asked, perplexed.  "There is a new pup that will be challenging
Alex for the alpha intact position?"

"Yes," Chuck replied as he stood up.  "James took on a new pup a few weeks
ago named Boar.  Some stray from the streets.  You should see him.  He's on
the chubby side but covered in thick fur with well-developed muscles in his
arms and chest and huge feet strapped to his thighs.  He sports a massive
set of low-hanging balls with a thick, uncut, thick cock at least ten
inches long."

"Bigger than Alex? Kevin asked in astonishment.

"Oh, yes," Chuck replied with a grin.

"I see!" Kevin asked.  "Yeah, it would be a shame to geld that sort of
equipment."

"James thinks he can best Alex, so the competition has been arranged,"
Chuck replied.

"Well, it has been over two years since Alex won the top spot from pup
Coby," Kevin said.  "He is due for a challenge anyway.  It's good for the
alphas to prove their worth repeatedly."

"Yeah, I am looking forward to the event," Chuck replied.

"Well, we will be there," Kevin replied.  "I'll bring my money."

"Good deal!" Chuck replied as he looked down.

Zeus was panting as he sat ass to ass with Jake.  Chuck reached down and
felt where the knot was buried deep in the boy and could feel the pulsing
as cum was still being injected.

"Looks like Zeus will be taking his time today," Chuck said.  "Shall we
grab a beer while they finish mating?"

"Yeah, come on inside," Kevin replied.

As the two men left, Jake hung his head.  The heat from the fluids filling
his lower colon was noticeable.  He could also feel the pulse of the knot
as blood engorged within it, locking him to the dog behind him.  Zeus was
in no hurry to move, and Jake was unsure what the dog would do if he tried
to move, so he sat perfectly still.  He looked below him and could almost
detect his abdomen distending as the seed was being delivered inside him.
He then considered the conversation he had overheard.  What was involved in
a dominance challenge?  It sounded like a big deal.  Jake remembered Alex
being a sizeable human pup with dark skin, a muscled chest, large balls,
and a huge cock that looked as thick as a beer can.  He remembered being
mounted by Alex at the end of his initiation, feeling the knot that had
been formed at the base of the boy's shaft.  What had that been made of?
How had it been done?  As he felt Zeus's bulge inside him, he became
aroused, and his shriveled nub started to drip.

"I want Alex's knot again," Jake thought.  "I need it.  I hope I get
another chance."
